Selecting installation location
• System air conditioner may cause static noise when listening to AM stations. Therefore, select an installation
location for indoor unit where electrical wiring can be done while keeping certain distance from a radio,
computer and stereo equipment.
- Especially, keep the unit at least 3m(9.84inch) away from the electrical equipment in an area with weak
electromagnetic waves and put the main power cable and communication cables in a separately installed
protection tube.
- Make sure that there is no equipment that generates electromagnetic waves. If not electromagnetic waves
may cause problem to the control systems which may lead to air conditioner malfunction. (Example: Remote
control sensor of the indoor unit may not receive the signal very well, due to ballast stabilizer of the lighting
equipment.)
• In regions with heavy snowfall, make sure to install the outdoor unit where there is no concerns of direct
snowfall on the outdoor unit. Also, build higher base support so that accumulated snow does not block the air
inlet or the heat exchanger.
• R-410A refrigerant is a safe, nontoxic and nonammable refrigerant. However, if the place holds any concerns for
exceeding dangerous level of refrigerant concentration in case of refrigerant leakage, extra ventilation system is
required.
• When you install the outdoor unit in a high places such as roof, install fence or guardrail around it. When there is
no fence or guardrail, service person could fall.
• Do not install the product in places where corrosive gases such as sulfur oxides, ammonia, and sulfurous gas are
produced. (e.g. Toilet outlet, ventilation opening, sewage works, dyeing complex, cattle shed, sulfuric hot spring,
nuclear power plant, ship etc.) When installing the product in those places, contact an installation specialty
store as the copper pipe and brazing part will need additional corrosion proof or anti-rust additive to prevent
corrosion.
• Make sure to keep away inammable materials (such as wooden materials, oil etc.) around the outdoor unit.
When there's re, those inammable material will easily catch the re and may pass it on to the product.
• Depending on the condition of power supply, unstable power or voltage any cause malfunction of the parts or
control system. (At the ship or places using power supply from electric generator...etc)
• Make sure to install MCU when using HR products.
• When you select the location to install MCU, the location is far away from indoor rooms because the refrigerant
running of MCU may create noise.

Base construction and installation of the outdoor unit
• Make sure to remove the wooden pallet before installing the outdoor unit. If you do not remove the wooden
pallet, there is risk of re during welding the pipes. If the outdoor unit is installed with wooden pallet on, and
it was used for long period time, wooden palette may break and cause electrical hazard or high pressure may
damage the pipes.
WARNING
❋ Fix an outdoor unit rmly on the base ground with anchor bolts.
❋ Manufacturer is not responsible for the damage occurred by not following the installation standards.
1. Make sure that the height of the base ground is 200mm or higher to protect the outdoor unit from rain water or other
external conditions. Also, install a draining pit around the base ground and connect the drain pipe to the drainage.
2. Considering the vibration and weight of the outdoor unit, strength of the base ground must be strong to prevent noise
and the top surface of it should be at.
3. Base ground should be 1.5 times larger than the bottom of the outdoor unit.
4. Outdoor unit must be xed rmly so that it can withstand the wind speed of 30m/s. If you cannot x the outdoor unit on
the base ground, x it by side or use extra structure.
5. In heating operation, defrost water may form so you must really care about the drainage and waterproong the oor. To
prevent defrost water from stagnating or freezing, construct a drainage with over 1/50 slope. (Ice may form on the oor
in winter time.)
6. It is necessary to add wire mesh or steel bar during concrete construction for the base ground to prevent damages or
cracks.
7. When installing multiple outdoor units at the same place, construct a H beam or an anti-vibration frame on the base
ground to install the outdoor unit.
8. After installing a H beam or an anti-vibration frame, apply corrosion protection and other necessary coating.
9. When concrete construction for outdoor unit installation is completed, install an anti-vibration pad (t=20mm/0.78 inch or
more) or an anti-vibration frame to prevent vibration of the outdoor unit from transferring to the base ground.
10. Place the outdoor unit on a H beam or an anti-vibration frame and x it with the bolt, nut and washer. (The bearing force
has to be over 3.5kN)

Refrigerant pipe installation
• When installing, make sure there is no leakage. When collecting the refrigerant, stop the compressor rst before
removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works
with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle
abnormally high which may lead to explosion and injury.
WARNING
Refrigerant pipe work
f The length of refrigerant pipe should be as short as possible and the height dierence between an indoor and outdoor
unit should be minimized.
f Piping work must be done within allowable piping length, height dierence, and the allowable length after branching.
f The pressure of the R-410A is high. Use only certied refrigerant pipe and follow the installation method.
f After installing the pipes, calculate the total length of the pipe to check if additional refrigerant is needed. When you need
to charge the additional refrigerant, make sure to use R-410A refrigerant.
f Use clean refrigerant pipe and there shouldn’t be any harmful ion, oxide, dust, iron content or moisture inside pipe.
f Use tools and accessories that t on R-410A only.

Selecting refrigerant pipe
First branch joint
Increase the main
pipe size
f Install the refrigerant pipe according to main pipe size of each outdoor unit capacity.
f When the pipe length (including elbow) between an outdoor unit and the farthest indoor unit exceeds 90m (295.28ft),
you must increase the size of the pipe (main pipe) by one grade which connects between the outdoor unit to the rst
branch joint.
f For H/R model, When the pipe length (including elbow) between an outdoor unit and the farthest indoor unit exceeds
90m, you must increase the size of the liquid pipe by one grade among the pipes(main pipe) which connects between
the outdoor unit to the rst branch joint.
